I don’t know of a good, reliable way to get a token with the scopes you want without creating your own app. However, that doesn’t mean you have to create a full-fledged application; you really only need to create an app so you have a client ID and client secret. You can stay in what Strava calls “single player mode” and either create a small script to get a token, or use the swagger playground to get one (https://developers.strava.com/playground)

If you take the scripting approach, I think the most accessible option would be to use the Python stravalib. There is excellent documentation on it and a lot of examples online (you could probably even get chatgpt to create mostly working code for you). You can use the localhost option to authorize your app and get a token and refresh token. Once you’ve got a refresh token you won’t have to go through the process again, you can just use it in the Python code to get a new token afters your expires. Tie that in with the powershell script and you should be good to go.
